After capturing the data traffic, the replicator may replicate the effect of the data traffic on mobile devices or other devices and take an appropriate corrective action.

CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to and is a continuation of U.S. patent application Ser. No. 16/400,141 filed May 1, 2019. The contents of the foregoing are hereby incorporated by reference into this application as if set forth herein in full.

BACKGROUND

Networks, such as 5G, may be designed to segment traffic into a control plane and user plane structure. Traffic from mobile devices may traverse gNodeBs and then may be delivered to the user plane serving gateway (e.g., user-SGW) after attachment and authentication. U-SGW's may be virtual network functions (VNFs). U-SGW's may be implemented in multiple regional datacenters in response to user demand and in order to optimize data traffic. Traffic delivered to and from user plane network elements may be unprotected from malicious software that may cause poor performance, malicious attacks, or errors.

SUMMARY

The user plane replicator (UPR) may capture and evaluate data traffic when it enters a communication network. The UPR may capture and evaluate data traffic before it affects the core network or before it is delivered to the end device (e.g., mobile device). After capturing the data traffic, the UPR may replicate the effect of the data traffic on mobile devices or other devices and take an appropriate corrective action, if needed.

In an example, an apparatus may include a processor and a memory coupled with the processor that effectuates operations. The operations may include obtaining an indication that a first device is connected with a network; based on the first device connecting with the network, obtaining redirected data traffic, wherein the redirected traffic is from the device to a second device; simulating the data traffic on a virtual machine that replicates the image of the second device; based on the simulating, determining a risk score for the data traffic; and based on the risk score, sending instructions to not allow the data traffic to be sent to the second device.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to limitations that solve any or all disadvantages noted in any part of this disclosure.

DETAILED DESCRIPTION

Internet of things (IoT) devices, autonomous vehicles (AVs), or other end devices may be more susceptible to malicious hackers based on their possible repetitive contact or accessibility with end users without initial screening for malicious intent. Further, because any hack of IoT devices, AVs, or mobile devices may result in financial loss, extensive property damage, severe injury, or loss of human life, it is even more important that these end devices are secure. For example, a hacked IoT device may release toxins in the air that may be harmful to humans or release water that may cause major property damage. In another example, AVs (e.g., an autonomous car) may be maliciously or dangerously configured to go speeds of 80 mph in a 35 MPH zone or travel on sidewalks instead of streets. In another example associated with an SMS text between mobile phones, while most SMS text may be displayed as text or an emoji on a remote mobile phone user display, a maliciously configured phone may activate financial transfer programs that should not be activated. As disclosed herein, a user plan replicator (also referred herein as replicator) may create images of devices connected with a network, capture data traffic emanating from the devices, and determine whether to forward the data traffic based on virtual simulations. The capture and subsequent simulation may be done before data traffic enters the core network.

FIG. 1 illustrates an exemplary system that may implement a user plane replicator. System 100 may include user plane replicator (UPR) 101, mobile device 106, base station 105, mobile device 104 (e.g., phone or laptop), IoT device 103, or AV 102. All such devices may be communicatively connected with each other via network 107, base station 105, base station 108, or the like. AV 102 may be a vehicle designed for air, land, or water. Examples of apparatuses that may fall into the scope of IoT device 103 may include connected security systems, thermostats, cars, electronic appliances, lights in household and commercial environments, alarm clocks, speaker systems, vending machines, and pressure sensors and release valves, among other things. It is contemplated that system 100 may include a wired network or wireless network (e.g., 5G, LTE, Wi-Fi). Replicator 101 (also referred herein as UPR 101) may include an image of each apparatus (e.g., IoT device 103, mobile device 106, base station 105, mobile device 104, IoT device 102, or AV 201) connected with network 107, which may be apparatuses within a core network, access network, or local area network. There may multiple replicator 101s distributed throughout a network and they may exchange images with each other as necessary. Each apparatus image may be replicated as a virtual machine (VM) 109 or virtual network function (VNF) 110 that may simulate the functions of the end apparatuses (e.g., IoT device 103 or AV 102).

FIG. 2 illustrates an exemplary method that uses a user plane replicator. At step 111, AV 102, for example, may connect to network 107 and be authenticated. At step 112, replicator 101 may determine if it already has an authenticated image of AV 102. This may be determined by comparing a first image of AV 102 to an already possessed first replicated image of AV 102 in VM 109 (or VNF 110) on replicator 101. If the first image matches the first replicated image, then replicator 101 may use the first replicated image for any future simulations. The comparison may be of identifiers, hash function results, or the like associated with the first image and the first replicated image. At step 113, an image of AV 102 (e.g., the first image) may be uploaded to replicator 101 (e.g., VM 109) to become the first replicated image. The first image may be replicated if there is no image of AV 102 already in replicator 101 or there is a new image (e.g., second image) on AV 102 that should be replicated into a second replicated image. The new image may be because of a software update of AV 102.

At step 114, replicator 101 may determine the risk score (e.g., worthiness) of data traffic to AV 102 from mobile device 106 (or vice versa). Replicator 101 may obtain data traffic from mobile device 106 and simulate the functions of AV 102 using VM 109. There may be expected results based on the simulation. In example, based on the data traffic from mobile device 106, a speaker in AV 102 should project audio (e.g., a voice) sourced from mobile device 106. Replicator 101 may score (e.g., to get a risk score) the simulated interaction of VM 109 (with the first replicated image) to what is expected to happen. The expectation may be based on previous actions for devices similar to AV 102 or specific to AV 102. For example, the actions may be based on machine learning or artificial intelligence. The score may indicate the risk of negative consequences to people or property if the data traffic (e.g., commands or other data) are sent to AV 102. The score may further be influenced based on a threat level of the action that would be taken by AV 102. For example, increasing the speed of AV 102 over the legal speed of the road (or air way) may be considered a high threat level, while turning on the inside light of the vehicle may be considered a low threat level. The threat level may be a factor that determines whether the risk score is high (e.g., 60%), low (e.g., 10%), medium (e.g., 35%), or the like.

At step 115, replicator 101 may allow or not allow the data traffic obtained in step 114 to proceed to AV 102, based on the score being within a threshold number. In a first example, if the score is in the low range then data traffic is allowed. In a second example, if the score is in the high range (e.g., above 59%) then the data traffic is not allowed. In a third example, if the score is in the medium range (e.g., between 34 and 59%), then an alert may be sent to an authorized user associated with AV 102 (e.g., occupant of AV 102 or administrator for AV 102) to authorize the data traffic. In a fourth example, being above or below a certain number of data traffic flows indicated to be medium or high (e.g., three previous traffic flows with the same risk score) may trigger allowing, not allowing, or sending an alert.

At step 116, when the data traffic is allowed then replicator 101 may send the data traffic to AV 102. At step 117, when the data traffic not allowed then replicator 101 may remedy the issue with the first image of AV 102. For example, replicator 101 may send instructions to AV 102 to install a previous validated image (e.g., a basic default image). The previous validated image may be stored on replicator 101 or some other device in system 100, such as another server (not shown), a nearby AV (not shown), mobile device 104, or the like.

FIG. 3 illustrates an exemplary method that uses a user plane replicator. There may be times where replicator 101 is only used based on certain factors, which is described in more detail herein. At step 121, there may be a determination whether data traffic (e.g., traffic obtained from mobile device 106) should be directed to VM 109 to simulate AV 102. VM 109 may have a first replicated image and AV 102 may include a matching first image. This determination may be based on one or more different factors. For example, with reference to AV 102 being used as a ride hailing service, the factors may include number of trips, total number of people for trips within a period, or total number of people within AV 102 for a trip, detected number of connections via Wi-Fi, Bluetooth, or the like, or GPS coordinates of mobile devices within a radius of AV 102, among other things. The aforementioned factors may be significant because the increased number of interactions with end users may increase the possibility of interacting with users that have malicious intent (or have hacked devices that are compromised) interact with AV 102. Additional factors may include period of time since last simulation, travel history of AV 102 riders within a period, number of packages delivered by AV 102, type of packages delivered by AV 102, destination of AV 102, average risk score in a period, geographical location (e.g., proximate to another device, such as within 10 feet), or type of applications active on mobile device 104, IoT device 103, or AV 102, among other things. It is contemplated that disclosed factors may be associated with any of the devices described herein and their use may be influenced by machine learning or artificial intelligence.

At step 122, based on the factors of step 121, the data traffic is directed to VM 109 to be simulated. At step 123, based on the simulation of the data traffic, determining a risk score for the data traffic. At step 124, based on the risk score, allowing or not allowing the data traffic. Steps of FIG. 2 and FIG. 3 may be combined or skipped as necessary. Replicator 101 or other network devices may perform all or some of the steps as described in FIG. 2 and FIG. 3.

It is contemplated that there may be an attempt to send data traffic remotely through a core network or directly (e.g., point-to-point communication). For example, mobile device 106 may remotely send to mobile device 104 through network 107 or directly send via Wi-Fi or Bluetooth. Even in the aforementioned situations, replicator 101 may be used. In a scenario with regard to attempted direct communication, AV 102 may be redirect data traffic from nearby mobile device 104 (e.g., rider in AV 102) to replicator 101 before accepting the data traffic. It is further contemplated that replicator 101 may be used with any mix of mobile devices, IoT devices, AVs, or other devices.

In a 5G context, UPR 101 may capture and evaluate data traffic when it exits the U-SGW and before it is delivered to the mobile device (e.g., UE). UPR 101 may capture and evaluate all data traffic before it affects the 5G core network. On the reverse flow, UPR 101 may evaluate data traffic before it is delivered to mobile device 106. UPR 101 may replicate the effect of the data traffic on mobile devices and take appropriate action such as blocking or modifying traffic, capturing the traffic for Communications Assistance for Law Enforcement Act (CALEA) purposes, or improving the performance of the network by compressing data or other data manipulation. Using UPR 101, service providers may achieve efficiencies in the network and potentially offer new services associated with improving the performance and security of mobile devices, IoT devices, or AVs, among other devices connected with the network.

UPR 101 may act as a Big Data repository for central collection of end-user activity. The effect of malicious code may be evaluated before it hits the 5G Core Network and the mobile device. In the event of a malicious attack to the network, UPR 101 may filter traffic and shut off network traffic to a selected number of devices affected instead of the whole network. UPR 101 may have an Artificial Intelligence (AI) machine functionality in which it learns the behavior of connected devices generally for a category of devices or specific to a particular device. Based on this learning, UPR 101 may determine the appropriate risk score for the data traffic and whether to allow the data traffic to proceed within a service provider network. It is contemplated herein that the replication and simulation may be done for end devices in the communication network of a service provider, as well as intermediary devices (MME, PGW, SGW, eNodeB, gNodeB, etc.) along a communications path of the network.

Also note that in 5G network elements may be considered “images” that are stored in containers. In other words, they may be considered not “real” machines but rather virtual network functions (VNFs). Images may be used to represent VNFs. These images may be moved in and out of worker machines who conduct the real work processed. The images may be stored in containers. Containers may be considered programs which provide the work environment, so images can be moved in an out for execution in worker nodes. The process of creating “worker nodes” and moving images in and out of containers residing in worker nodes is often called orchestration.

Virtual machines can be isolated software containers, operating independent of other virtual machines. Such isolation can assist in realizing virtual-machine-based virtual environments that can execute applications and provide services with availability, flexibility, and security, in some cases, surpassing those on traditional, non-virtualized systems. Virtual machines can encapsulate a complete set of virtual hardware resources, including an operating system and all its applications, inside a software package. Encapsulation can make virtual machines quite portable and manageable. Indeed, virtual machines can be hardware-independent, and can be portably provisioned and deployed on one of multiple different computing devices, operating systems, and environments. Indeed, depending on the availability of computing devices within a cloud environment (e.g., UPR 101) a particular virtual machine 109 may be provisioned on any one (or multiple) of the devices included in a cloud environment.

In some instances, a virtual machine manager (not shown) may be provided in connection with a cloud computing system (or other system hosting virtual infrastructure). Virtual machine managers, or hypervisors, may be implemented as software- and/or hardware-based tools used in the virtualization of hardware assets (i.e., as virtual machines 109) on one or more host computing devices (e.g., UPR 101). A virtual machine manager may be used to run multiple virtual machines, including virtual machines with different guest operating systems, on one or more host computers (e.g., UPR 101). The virtual machine manager may provide a shared virtual operating platform for multiple virtual appliances and guest operating systems and enable a plurality of different virtual machines (and guest operating systems) to be instantiated and run on computing devices and hardware hosting virtual infrastructure (e.g., UPR 101 or mobile device 104). Further, virtual machine managers, in some instances may be run natively, or as “bare metal,” directly on host computing devices' hardware to control the hardware and to manage virtual machines provisioned on the host devices. In other instances, “hosted” virtual machine managers may be provided that is run within the operating system of another host machine, including conventional operating system environments. Lastly, a virtual component can be programmed to perform application specific functions that may be associated with microcontroller, sensor, motors, actuators, lighting, or radio frequency identification (RFID), among other things.

With the above in mind, VM 109 may be used or VNF 110 may be used. The simulation is done by the virtual image. Note that a virtual machine (VM) includes its own operating system. An example is VMWARE. A virtual image can be moved to “worker nodes” for execution. They do not need a full virtual machine environment. The images may be considered VNFs and can be stored in “container” products such as Docker. Therefore, there may be simulation of the data traffic on a VNF that may be a virtual machine, or a container image moved to a worker computing node for execution. The movement of these VNF images for execution is performed by orchestration software.

FIG. 5 depicts an exemplary diagrammatic representation of a machine in the form of a computer system 500 within which a set of instructions, when executed, may cause the machine to perform any one or more of the methods described above. One or more instances of the machine can operate, for example, as processor 302, user plane replicator (UPR) 101, mobile device 106, base station 105, mobile device 104, IoT device 103, AV 102, and other devices of FIG. 1. In some embodiments, the machine may be connected (e.g., using a network 502) to other machines.

It will be understood that a communication device of the subject disclosure includes broadly any electronic device that provides voice, video or data communication. Further, while a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methods discussed herein.

Computer system 500 may include a processor (or controller) 504 (e.g., a central processing unit (CPU)), a graphics processing unit (GPU, or both), a main memory 506 and a static memory 508, which communicate with each other via a bus 510.

FIG. 6A is a representation of an exemplary network 600. Network 600 (e.g., system 100) may comprise an SDN—that is, network 600 may include one or more virtualized functions implemented on general purpose hardware, such as in lieu of having dedicated hardware for every network function. That is, general purpose hardware of network 600 may be configured to run virtual network elements to support communication services, such as mobility services, including consumer services and enterprise services. These services may be provided or measured in sessions.

A virtual network functions (VNFs) 602 may be able to support a limited number of sessions. Each VNF 602 may have a VNF type that indicates its functionality or role. For example, FIG. 6A illustrates a gateway VNF 602 a and a policy and charging rules function (PCRF) VNF 602 b. Additionally or alternatively, VNFs 602 may include other types of VNFs. Each VNF 602 may use one or more virtual machines (VMs) 604 to operate. Each VM 604 may have a VM type that indicates its functionality or role. For example, FIG. 6A illustrates a management control module (MCM) VM 604 a, an advanced services module (ASM) VM 604 b, and a DEP VM 604 c. Additionally or alternatively, VMs 604 may include other types of VMs. Each VM 604 may consume various network resources from a hardware platform 606, such as a resource 608, a virtual central processing unit (vCPU) 608 a, memory 608 b, or a network interface card (NIC) 608 c. Additionally or alternatively, hardware platform 606 may include other types of resources 608.

While FIG. 6A illustrates resources 608 as collectively contained in hardware platform 606, the configuration of hardware platform 606 may isolate, for example, certain memory 608 c from other memory 608 c. FIG. 6B provides an exemplary implementation of hardware platform 606.

Hardware platform 606 may comprise one or more chasses 610. Chassis 610 may refer to the physical housing or platform for multiple servers or other network equipment. In an aspect, chassis 610 may also refer to the underlying network equipment. Chassis 610 may include one or more servers 612. Server 612 may comprise general purpose computer hardware or a computer. In an aspect, chassis 610 may comprise a metal rack, and servers 612 of chassis 610 may comprise blade servers that are physically mounted in or on chassis 610.

Each server 612 may include one or more network resources 608, as illustrated. Servers 612 may be communicatively coupled together (not shown) in any combination or arrangement. For example, all servers 612 within a given chassis 610 may be communicatively coupled. As another example, servers 612 in different chasses 610 may be communicatively coupled. Additionally or alternatively, chasses 610 may be communicatively coupled together (not shown) in any combination or arrangement.

The characteristics of each chassis 610 and each server 612 may differ. For example, FIG. 6B illustrates that the number of servers 612 within two chasses 610 may vary. Additionally or alternatively, the type or number of resources 610 within each server 612 may vary. In an aspect, chassis 610 may be used to group servers 612 with the same resource characteristics. In another aspect, servers 612 within the same chassis 610 may have different resource characteristics.

Given hardware platform 606, the number of sessions that may be instantiated may vary depending upon how efficiently resources 608 are assigned to different VMs 604. For example, assignment of VMs 604 to particular resources 608 may be constrained by one or more rules. For example, a first rule may require that resources 608 assigned to a particular VM 604 be on the same server 612 or set of servers 612. For example, if VM 604 uses eight vCPUs 608 a, 1 GB of memory 608 b, and 2 NICs 608 c, the rules may require that all of these resources 608 be sourced from the same server 612. Additionally or alternatively, VM 604 may require splitting resources 608 among multiple servers 612, but such splitting may need to conform with certain restrictions. For example, resources 608 for VM 604 may be able to be split between two servers 612. Default rules may apply. For example, a default rule may require that all resources 608 for a given VM 604 must come from the same server 612.

An affinity rule may restrict assignment of resources 608 for a particular VM 604 (or a particular type of VM 604). For example, an affinity rule may require that certain VMs 604 be instantiated on (that is, consume resources from) the same server 612 or chassis 610. For example, if VNF 602 uses six MCM VMs 604 a, an affinity rule may dictate that those six MCM VMs 604 a be instantiated on the same server 612 (or chassis 610). As another example, if VNF 602 uses MCM VMs 604 a, ASM VMs 604 b, and a third type of VMs 604, an affinity rule may dictate that at least the MCM VMs 604 a and the ASM VMs 604 b be instantiated on the same server 612 (or chassis 610). Affinity rules may restrict assignment of resources 608 based on the identity or type of resource 608, VNF 602, VM 604, chassis 610, server 612, or any combination thereof.

An anti-affinity rule may restrict assignment of resources 608 for a particular VM 604 (or a particular type of VM 604). In contrast to an affinity rule—which may require that certain VMs 604 be instantiated on the same server 612 or chassis 610—an anti-affinity rule requires that certain VMs 604 be instantiated on different servers 612 (or different chasses 610). For example, an anti-affinity rule may require that MCM VM 604 a be instantiated on a particular server 612 that does not contain any ASM VMs 604 b. As another example, an anti-affinity rule may require that MCM VMs 604 a for a first VNF 602 be instantiated on a different server 612 (or chassis 610) than MCM VMs 604 a for a second VNF 602. Anti-affinity rules may restrict assignment of resources 608 based on the identity or type of resource 608, VNF 602, VM 604, chassis 610, server 612, or any combination thereof.

Within these constraints, resources 608 of hardware platform 606 may be assigned to be used to instantiate VMs 604, which in turn may be used to instantiate VNFs 602, which in turn may be used to establish sessions. The different combinations for how such resources 608 may be assigned may vary in complexity and efficiency. For example, different assignments may have different limits of the number of sessions that can be established given a particular hardware platform 606.

For example, consider a session that may require gateway VNF 602 a and PCRF VNF 602 b. Gateway VNF 602 a may require five VMs 604 instantiated on the same server 612, and PCRF VNF 602 b may require two VMs 604 instantiated on the same server 612. (Assume, for this example, that no affinity or anti-affinity rules restrict whether VMs 604 for PCRF VNF 602 b may or must be instantiated on the same or different server 612 than VMs 604 for gateway VNF 602 a.) In this example, each of two servers 612 may have sufficient resources 608 to support 10 VMs 604. To implement sessions using these two servers 612, first server 612 may be instantiated with 10 VMs 604 to support two instantiations of gateway VNF 602 a, and second server 612 may be instantiated with 9 VMs: five VMs 604 to support one instantiation of gateway VNF 602 a and four VMs 604 to support two instantiations of PCRF VNF 602 b. This may leave the remaining resources 608 that could have supported the tenth VM 604 on second server 612 unused (and unusable for an instantiation of either a gateway VNF 602 a or a PCRF VNF 602 b). Alternatively, first server 612 may be instantiated with 10 VMs 604 for two instantiations of gateway VNF 602 a and second server 612 may be instantiated with 10 VMs 604 for five instantiations of PCRF VNF 602 b, using all available resources 608 to maximize the number of VMs 604 instantiated.

Consider, further, how many sessions each gateway VNF 602 a and each PCRF VNF 602 b may support. This may factor into which assignment of resources 608 is more efficient. For example, consider if each gateway VNF 602 a supports two million sessions, and if each PCRF VNF 602 b supports three million sessions. For the first configuration—three total gateway VNFs 602 a (which satisfy the gateway requirement for six million sessions) and two total PCRF VNFs 602 b (which satisfy the PCRF requirement for six million sessions)—would support a total of six million sessions. For the second configuration—two total gateway VNFs 602 a (which satisfy the gateway requirement for four million sessions) and five total PCRF VNFs 602 b (which satisfy the PCRF requirement for 15 million sessions)—would support a total of four million sessions. Thus, while the first configuration may seem less efficient looking only at the number of available resources 608 used (as resources 608 for the tenth possible VM 604 are unused), the second configuration is actually more efficient from the perspective of being the configuration that can support more the greater number of sessions.

To solve the problem of determining a capacity (or, number of sessions) that can be supported by a given hardware platform 605, a given requirement for VNFs 602 to support a session, a capacity for the number of sessions each VNF 602 (e.g., of a certain type) can support, a given requirement for VMs 604 for each VNF 602 (e.g., of a certain type), a give requirement for resources 608 to support each VM 604 (e.g., of a certain type), rules dictating the assignment of resources 608 to one or more VMs 604 (e.g., affinity and anti-affinity rules), the chasses 610 and servers 612 of hardware platform 606, and the individual resources 608 of each chassis 610 or server 612 (e.g., of a certain type), an integer programming problem may be formulated.

As described herein, a telecommunications system wherein management and control utilizing a software designed network (SDN) and a simple IP are based, at least in part, on user equipment, may provide a wireless management and control framework that enables common wireless management and control, such as mobility management, radio resource management, QoS, load balancing, etc., across many wireless technologies, e.g. LTE, Wi-Fi, and future 5G access technologies; decoupling the mobility control from data planes to let them evolve and scale independently; reducing network state maintained in the network based on user equipment types to reduce network cost and allow massive scale; shortening cycle time and improving network upgradability; flexibility in creating end-to-end services based on types of user equipment and applications, thus improve customer experience; or improving user equipment power efficiency and battery life—especially for simple M2M devices—through enhanced wireless management.

While examples of a telecommunications system in which messages associated with the user plane replicator can be processed and managed have been described in connection with various computing devices/processors, the underlying concepts may be applied to any computing device, processor, or system capable of facilitating a telecommunications system. The various techniques described herein may be implemented in connection with hardware or software or, where appropriate, with a combination of both. Thus, the methods and devices may take the form of program code (i.e., instructions) embodied in concrete, tangible, storage media having a concrete, tangible, physical structure. Examples of tangible storage media include floppy diskettes, CD-ROMs, DVDs, hard drives, or any other tangible machine-readable storage medium (computer-readable storage medium). Thus, a computer-readable storage medium is not a signal. A computer-readable storage medium is not a transient signal. Further, a computer-readable storage medium is not a propagating signal. A computer-readable storage medium as described herein is an article of manufacture. When the program code is loaded into and executed by a machine, such as a computer, the machine becomes a device for telecommunications. In the case of program code execution on programmable computers, the computing device will generally include a processor, a storage medium readable by the processor (including volatile or nonvolatile memory or storage elements), at least one input device, and at least one output device. The program(s) can be implemented in assembly or machine language, if desired. The language can be a compiled or interpreted language, and may be combined with hardware implementations.

The methods and devices associated with a telecommunications system as described herein also may be practiced via communications embodied in the form of program code that is transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as an EPROM, a gate array, a programmable logic device (PLD), a client computer, or the like, the machine becomes an device for implementing telecommunications as described herein. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique device that operates to invoke the functionality of a telecommunications system.

While a telecommunications system has been described in connection with the various examples of the various figures, it is to be understood that other similar implementations may be used or modifications and additions may be made to the described examples of a telecommunications system without deviating therefrom. For example, one skilled in the art will recognize that a telecommunications system as described in the instant application may apply to any environment, whether wired or wireless, and may be applied to any number of such devices connected via a communications network and interacting across the network. Therefore, a telecommunications system as described herein should not be limited to any single example, but rather should be construed in breadth and scope in accordance with the appended claims.

In describing preferred methods, systems, or apparatuses of the subject matter of the present disclosure—user plane replicator—as illustrated in the Figures, specific terminology is employed for the sake of clarity. The claimed subject matter, however, is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose. In addition, the use of the word “or” is generally used inclusively unless otherwise provided herein.

This written description uses examples to enable any person skilled in the art to practice the claimed subject matter, including making and using any devices or systems and performing any incorporated methods. The patentable scope is defined by the claims, and may include other examples that occur to those skilled in the art (e.g., skipping steps, combining steps, or adding steps between exemplary methods disclosed herein). Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.

Methods, systems, and apparatuses, among other things, as described herein may provide for determining whether to send data traffic through or to a device. A method, system, computer readable storage medium, or apparatus may obtain an indication that a first device is connected with a network; based on the first device connecting with the network, obtain redirected data traffic, wherein the redirected traffic is from the device to a second device; simulate the redirected data traffic on a virtual machine that replicates the image of the second device; based on the simulating, determine a risk score for the redirected data traffic; and based on the risk score, send instructions to not allow the redirected data traffic to be sent to the second device. The obtaining the redirected data traffic may be further based on the first device being proximate to the second device or the first device running multiple other applications that are not related to the application that originated the redirected data traffic. The second device may be an autonomous vehicle or an internet of things device. Further the apparatus may send an alert to a third device to remedy the image of the second device, wherein the remedy may include sending an updated image to the second device to replace the current image of the second device. The replicator may alter the data sent to the device based on what it is learned after execution. All combinations in this paragraph (including the removal or addition of steps) are contemplated in a manner that is consistent with the other portions of the detailed description. The functions may be distributed over multiple devices.
